When I finished the modeling process, I started to set up the lighting. I decided to use VRaySun (Fig.05). I also added a V-Ray dome light. I turned off Affect Diffuse and Specular, and I left Reflection on. This light just gave me reflections, so the main light was going to be the sun. To achieve this I put in an HDRI of a city that I found on internet, as initially, I was planning to make a little environment of a city (Fig.06).

You can achieve the first impression of you work using V-Ray RT. Change your renderer, next to Activate Shade, to V-Ray RT. Don't forget to change the mode, from Production to Activeshade mode. A new window will appear and then in a few seconds you will get a previz, which is close to high render quality. The magic of this is that you can move your camera and the render will automatically refresh. It's a powerful tool to refine your composition, change materials or tweak the lighting. I wanted some contrast so I changed the intensity of the sun (Fig.07).

When I was happy with the camera position, I started the environment. I used these two photos from CGTextures as a reference (Fig.08 - 09). The modeling was quite easy; it was just an edit poly with some extrusions. What is important here is the texture. I added an Unwrap modifier to the geometry and fitted all the pieces to the texture. In this case I used Planar projections, which got the work done (Fig.10).
